To all whom it may con/cern:

Beit known that I, WILLIAM H. MITCHELL,

of Boston, county of Suffolk,and State of Massachusetts, have inventedan Improvement in Tires, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

The present invention relatesto a rubber tire, and is embodied in a tireof that class in which the tire proper is supported in a channel-ironupon the `rim of the wheel and held in position by a fastening-bandwhich extends longitudinally through the rubber, the ends of the said`band being drawntogether and fastened after the tire is inplace.

The invention is mainly embodied in a novel fastening device for 4theends of the band, which ends are connected together independently of thechannel-iron or Wheel-rim, so that from longitudinal movement in thechanneliron.

It is the object of the invention to obtain a practical fastening devicewhich will firmly connect the ends of the bandand which may be easilyapplied.

The fastening device embodying the invention consists of a lockingmember the body portion of which is arranged to underlie the ends of thefastening-strip when the said ends are drawn together and is providedwith projections extending upward from the said body portion and adaptedto enter lateral notches formed in opposite sides of the fasteningstrip, the said projections being somewhat longer than the thickness ofthe fastening-strip, so that they can be bent down over the surface ofsaid strip after the parts are in place, thereby secu rely fastening allof the parts together. The body portion of the fastening device and theends of the locking projections are shown as comparatively thin, so thatwhen the said device is in place it does not materially enlarge thefastening-strip at that point, and consequently does not bulge the tire.

Figure l is a side elevation, partly in section,of the tire, thefasteningstrip and fastening member being shown in elevation. Fig. 2 isa sectional plan view of the same, and

stanno. 17,430. (Nomads.) H y r Fig; 3 atop plan view of the blank fromwhich the fastening memberis made.

In applying tires of this description to the Wheels the fastening-stripa is first inserted in the tire b, the latter then being compressed tireand strip are applied to the wheel the ends of the said strip will beexposed for a certain distance, as shown at the right-hand side of Fig.l, so that they are accessible for fastening purposes. In accordancewiththe invention the said strip (t is provided near each end With one ormore lateral notches t2 at opposite sides, which are arranged to beengaged by vertical projections c2 from a fastening device c, whichconsists of a strip of metal or other suitable material having a bodyportion c3 arranged to underlie the said strip for a certain distanceeach way from the point where the ends of said strip come together. Infastening the tire the said ends are drawn together and then forceddownward towardV the body portion c3 of the fastening member c, theprojections c2 entering the lateral recesses a2, and thus preventingindependent longitudinal movement of the two ends of the strip. Tocomplete the fastening, the said proj ections c2, which are arranged toextend above the top of the strip a, are bent over the top of the saidstrip, as indicated at the left-hand side of Figs. l and 2, and therubber tire is pulled over the fastening in the usual Way until the endsof said rubber tire come together. The main strain on such a fasteningdevice is the longitudinal strain caused by the tendency of the ends ofthe strip a to pull apart under the strain of the compressedi rubbertire, and in order to afford sufficient strength to withstand suchstrain without materially increasing the space occupied by the fasteningmember the main body portions of the projections c2 are made thickerthan the ends thereof,'so that When said ends are bent over the topofthe strip they add very slightly to the thickness of the completedfastening-band, although none of the strength required in the bodyportions of the said projections is sacriced.

To further increase the strength of the fastening device and to preventthe ends of the vand the ends pushed back, so that when the IOO Y nient,thethin bodyfportion ofV rthe fastening p device isv laterally extendedalongthe middle', v v as indicated at o45 so; as to be bentn'py-andjie;.theffatening-strp"whereftheendsthereof alongthe sides.' ofthe fastening-strip 0b, Whl l tended far'enjo'ngh tooverlie `tesomeextentY y fthe edges of Sthevstiip, as kshown at thefleft-y 119. t
